Determining the Solubility Product of Fe(OH)3: An Equilibrium Study with Environmental SignificanceMichelle Meighan, Joseph MacNeil, and Renee FalconerThis study explores the environmental impact of acidic mine drainage by investigating the relationship between pH and the aqueous solubility of heavy metals. Students precipitate Fe(OH)3 from acidic FeCl3 and NaOH and use the concentrations of ferric and hydroxide ionsdetermined through pH and flame spectroscopyto calculate the Ksp of Fe(OH)3.Meighan, Michelle; MacNeil, Joseph; Falconer, Renee. J. Chem. Educ.2008, 85, 254.

The Chemistry of Swimming Pool MaintenanceCarl Salter and David L. LanghusThis paper examines the key ideas behind swimming pool chemistry -- the central importance of pH and its effect on chlorine sanitation and calcium carbonate solubility. The paper also reviews the analytical procedures and common practices used to monitor and control pool chemistry or correct problems.Salter, Carl; Langhus, David L. J. Chem. Educ.2007, 84, 1124.

Solubility Rules: Three Suggestions for Improved UnderstandingBob BlakeMany general chemistry textbooks have errors or omissions in their rules for predicting solubility that the author highlights and attempts to correct. In addition, it is proposed that the following changes be made to the discussion of solubility so that students and teachers can have a greater understanding of solubility.Blake, Bob. J. Chem. Educ.2003, 80, 1348.

MiscellaneousAlyea, Hubert N.These twelve overhead projection demonstrations include rates of reactions, clock reactions, the effect of temperature and the presence of a catalyst on the decomposition of hydrogen peroxide, the relationship between viscosity and temperature, equilibria, solubility product, and the common ion effect.Alyea, Hubert N. J. Chem. Educ.1970, 47, A437.

The nature of dissolved silver acetateRamette, Richard W.This experiment is an attempt to identify the species of silver that exist in aqueous solutions of silver acetate.Ramette, Richard W. J. Chem. Educ.1966, 43, 299.

Variation of the solubility product constant with ionic strengthCarmody, Walter R.Describes the development of a demonstration of the constancy (under the right conditions) of the concentration solubility product and the effect of particle size on solubility, and an experiment for quantitatively demonstrating the effect of ionic strength on the concentration solubility product.Carmody, Walter R. J. Chem. Educ.1959, 36, 125.

The analyst and the inconstant constantsRingbom, AndersSimple theories taught to freshmen often do not agree well with experimental data; the author examines the case of equilibrium constants and elaborates on a method of dealing with this problem.Ringbom, Anders J. Chem. Educ.1958, 35, 282.
